v. Promoted for two times and received two professional excellence awards in 5 five years
vi biggest professional achievement over the past five years is the conceptualization of a business model that drastically improve the appeal of the ebusiness standard to small and medium enterprises.

8.Questions
1. Should I retake my GMAT to improve my chance of getting in those ultra competitive schools?
2. I am not sure how unique my profile is as to warrant some attention from the adcom.. I am also quite confused what are the specific aspects that I should emphasize to show my edge?
3. When I look at my diverse work experiences, I am kind of worried that the adcom might view it as a lack of focus. Can you advise?
4. I am thinking to apply to only 3 universities, one each in the bands of long shot, competitive and safety. Do you have any recommendations?
